Specification of Letters Patent. Patented Api'. 2Q,

Application led May 23, 1913. Serial No. 769,513.

To al? whom it may concern Be it known that I, BERNHARD LERBACK, asubject of Norway, residing at Mandan, in the county of Morton and Stateof North Dakota, have invented certain new and useful improvements inPermutation-Locks, of which the following is a specification, referencebeing had therein to the accompanying drawing.

rlhis invention relates to locks and has special reference to that classof locks that are used on trunks, suitcases, etc.

The object of this invention is to provide a combination lock that willbe as eiiicient as the ordinary key locks that are used 0n trunks andsuitcases.

Another object of this invention is to provide a combination made of theminimum number of parts.

`With these and other objects in view this invention consists in generalof certain novel constructions, combinations, and arrangements of parts,as will be hereinafter fully described, illustrated in the accompanying`drawings, and specifically claimed.

In the accompanying drawings: Figure 1 is a front elevation of myimproved lock mounted on a trunk, suitcase etc. Fig. 2 is a verticalsection taken on line 2--2, Fig. l. Fig. 3 is a front elevation showinga part of Fig. 4 is an enlarged section taken on line 4.-4, Fig. 3. Fig.5 is a perspective view of the locking frame used in this improved lock.Fig. 6 is a front elevation of one ofthe disks used with this Y device.

Referring to the accompanying drawings by reference numerals, 10indicates a portion of the body of the trunk, suitcase or otherreceptacle and the cover portion of the receptacle is shown indicated by11. A casing 12 providing laterally extending wings 18 through which thesecuring means 14 pass has a pocket formed therein. Slidably mounted inthe pocket 15 of the casing is the locking frame 16 which has a U-shaped head 17 at its upper end. The vertically extending members 18 ofsaidl head have their outer faces resting flat against the sides of thepocket 15 which prevents a wabbling of the locking frame. Connected tothe head 17 by the rod 19 is the base 2O which has its end faces restingagainst the Sides of the pocket so as to brace the locking frame in saidpocket. Formed on the under face of the base 2O is a downwardlyprojecting locking lug 20. A locking lip 21 is formed at the outer faceof the hori- Zent-al member of the U-shaped head of the locking frame.Wound around the connecting rod 19 is a coil spring 22 which restsagainst the under face of the head 17 and a bracket 23 that is formed inthe casing and is provided with an opening through which the rod 19passes. ln this manner it will be seen that the spring will normallyurge the locking frame upwardly and will thereby cause the device to beheld in such a manner as to easily engage the hasp Ll() when it isdesired. An operating pin passes through the slot 24e formed in thecasing 12 and engages the base 20 whereby the locking frame may be moveddownwardly when the combination has been worked.

Mounted on the outer face of the casing 12 is a circular dialy 25 whichhas a series of numerals on its face. A shaft 26 is rotatably carried bythe casing and has an operating knob 27 at its outer end. in indicator28 is provided for on the bearing disk The shaft 26 carries a primarydisk 3G that is provided with a collar 3l through which the screw 32passes to hold the disk 30 xedly upon the shaft 2b. An inwardlyextending` pin 33 is carried by the inner face of the primary disk 30for the purposes hereinafter described. The primary disk is also provided with a notch 34.' Loosely carried by the shaft 26 at its inner end isan auxiliary disk 35 having a plurality of flattened sides 3G. Thisloosely mounted disk also has a notch 37 and a forwardly extending pin3L.. The auxiliary disk being loosely mounted upon the shaft 26 allowsthe disk to easily rotate when so desired or may remain in one positionwhen it is desired to allow the same to remain stationary. ln order toretard the rotary movement of the primar7 and auxiliary disks there areprovided a pair of flat springs 39 secured to the casing which bear uponthe outer peripheries of the disks. Secured to the top or cover 11 ofthe receptacle is an ordinary vhasp lOwhic'h is pro vided on its innerface with a catch which engages the lip 21 of the locking frame.

When the device is in a locked position as shown in Fig. 2 to unlock thesame or move the locking frame downwardly so as to disengage the lip 21and the catch 4:1 of

the hasp 40 the shaft 26 is rotated by means locking disk 30 of the knob27 whereby the Y ticular number to' which the indicator carried by thebearing disk should point and by rotatingthe shaft so as to allow thisindicator to point atV the number, the operator will know that theauxiliary disk is in alinelment with the lug 20. When the auxiliary edisk has assumed this position it will remain the same as the spring 39will prevent the same from turning on the shaft 26. The shaft is thenrotated in the opposite direction, whereby the pins will becomeVdisengaged. When the primary disk has been turned far enough as shownby the indica tor, the operator will know that the notch in the primarydisk is registering with the notch in the auxiliary disk, the knob 24 isthen pushed downward, thus bringing the lug 20 in the alined notches andthe hasp may be swung outwardly thereby unlocking the cover.

It is obvious that many minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof and it is therefore not wished to confine theinvention to the exact form herein shown and described, but it is wishedto include all such as properly come within the scope claimed.

What is claimed is Y 1. A device of the class described comprising acasing having a pocket, a locking frame positioned within said pocket,said locking frame comprising a U-shaped head extending transverselyacross said pocket, a rod carried by the lower portion of said head, abase carried upon the lower end of said rod and extending transverselyacross said pocket, said base and head bearing upon the side portion ofsaid casing whereby said locking frame will be held against wabbling andwill be allowed to slide freely within said casing, a spring carriedupon said rod, said spring being adapted to exert an upward pressureupon said head whereby said locking frame will be normally urgedupwardly, a lug formed upon the lower portion of said base, meansengaging said lug for locking said frame in the upper portionlockingframe comprising a U-shaped head,

a rod depending from said head, a base carried Yupon saidrod, said baseand head t' ting snugly upon the side portions of said casing, a springmounted upon'said rod,

said spring engaging a portion vof said cas- Y ing-and engaging saidhead for normally urging said locking frame upwardly, said casing.provided with a slot in its forward portion, a pin passing through saidslot and engaging said base whereby said locking frame mayy be movedwhen the device is unlocked, means for releasably holding said frame ina locked position, said framerbeing adapted to engage a hasp. Y

3. A device of the class described com-` prising a casing having apocket,'a locking frame positioned within said pocket,

said

locking frame comprising va U-shaped head extending transversely acrosssaid pocket,

a rod carried by the lower portion of said head, a base carried upon thelower end of said rod and extending transversely across said pocket,said base and head bearing upon the side portion of said casing wherebysaid locking frame will be held against wabbling and will be allowed toslide freely within said casing, a spring carried upon said rod, saidspring being adapted to exert an upward pressure upon said head, wherebysaid locking frame will be normally urged upwardly, a lug formed uponthe lower portion of said base, permutation disks rotatably carriedwithin said pocket, said disks provided with notches formed in theirouter peripheries, said disks being adapted to be rotated so as tocauseV said notches to register with each other in alinement with saidlug, whereby the lug may be moved into said notches when it is desiredto move the locking frame, said frame being adapted to engage a haspwhen in a locked BERNHARD LERBAGK.
